As it stands expandarg may return with a non-NULL ifslastp which
then confuses any subsequent ifsbreakup user that doesn't clear
it directly.
What's worse, if we get interrupted before we hit ifsfree in
expandarg we will leak memory.
This patch fixes this by always calling ifsfree in expandarg
thus ensuring that ifslastp is always NULL on the normal path.
It also adds an ifsfree call to the RESET path to ensure that
memory isn't leaked.

When I try to split fields by tabs, dash doesn't honour multiple tabs
between fields as whitespace (at least that's how I interpret [1],
please correct me if I'm wrong).
#!/bin/sh
# "1\t2\t\t3"
TESTSTRING="1 2 3"
# only "\t"
IFS=" "
echo "$TESTSTRING" | while read p1 p2 p3; do
echo "p1=${p1}, p2=${p2}, p3=${p3}"
done

Previously we always expanded here-documents in a subshell. This is
contrary to the POSIX specification and how other shells behave. What's
more this slows down many expansions due to the extra fork (however, it
must be said that it is possible for it speed up certain expansions by
running it simultaneously with the command on two CPUs).
This patch move the expansion into the current shell environment.
Test case:
unset a
cat <<- EOF > /dev/null
${a=NOT}
EOF
echo ${a}BAD
Old result:
BAD
New result:
NOTBAD

This patch adds assignment operator support in arithmetic expansions. It
also changes the type used to intmax_t.

Because the parser does not recursively parse parameter expansion with respect
to quotes, we can't accurately determine quote status at parse time. This
patch works around this by moving the quote detection to run-time where we
do interpret it recursively.
Test case:
foo=\\
echo "<${foo#[\\]}>"
Old result:
<\>
New result:
<>

Previously code was added so that tilde expansion was carried out
parameter expansions within double quotes. This change was made
with reference the behaviour of bash at the time. Bash has since
be fixed so that this behaviour no longer occurs which is in line
with most other POSIX shells.
So this patch removes that behaviour in dash as well.
Test case:
unset a
echo "${a:-~root}"
Old result:
/root
New result:
~root

This change updates the BSD licence to the three-clause version since
NetBSD has already done so. This makes dash GPL-compatible.
It also adds Christos Zoulas (NetBSD ash maintainer) to the COPYING file.
I've added "copyright by Herbert Xu" to most files.
Finally all CVS IDs and inclusion of sys/cdefs.h have been removed.
The latter is needed for support of klibc.
